For some purposes a photon—a quantum of electromagnetic radiation can be treated as a classical electromagnetic wave train with energy au = ħw, where ħ is planck's reduced constant and w is the angular frequency of the wave. photons are circularly polarized. a. in einstein's mechanics the mass m of a particle of energy eand momentum p is given by the relation e? - p²c2 = m4, where c is the speed of light in vacuum. calculate the mass of the photon, defined in this way. b. the spin quantum number s of a particle is its spin angular momentum s divided by planck's reduced constant ħ. calculate the spin quantum number of the photon, thus defined

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?

Objects a and b are visible in the night sky. six months later they are still visible, but object b shows less parallax than object a. which object is closer? a. a b. b c. you would need to wait another six months in order to figure this out. d. you would need to know the objects' angular diameters in order to figure this out.
